Got the Billstein 5100's on the way, and Would like to AAL in the rear, I'm at 38,500 miles on the button and Doubt toyota will honor the TSB (even though I have the 75k extended warrantee (truck is a 2008).

Should I just get the Toyota AAL and have the shop install that with the 5100's or should I be looking at other companies offerings? Would I be better off going with the OEM part - I have read some are not happy with Toytec's offering, what are some of the other ones out there, those are the only two I know of/read about other than doing complete leaf pack swaps.

The overall goal was a modest 2" increase in ground clearance, so with the larger 265/70R17's and 1.5 inch (billsteins 5100's / 3 leaf progressive AAL) I should be sitting exactly like I want. Shocks are on the way, just gonna sit on it a day and do some more reading before pulling the trigger on the 3 Leaf AAL.

If you aren't under warranty then the TSB leafs are going to cost you $600 per side, at least that's what my dealer told me. I laughed in their face and walked out. I ended up getting the All-Pro 1.5" Leaf Springs from a member here for $200.
